Man, just have an engine built. Crate motors suck. seriously. Most of them, are slapped together, cheap barely adequate core engines. I used to HATE crate engines, and get really mad when someone would bring them up, or use that term. And, when womeone would come in, looking for an engine, then buy a crate engine instead of having me build them a precision, custom engine, it would bum me out, and make me mad. Funny thing is, I usualy see them the next year, to re-build it, port the heads, etc etc. They spend more than twice as much as they would have, if they would have had me build the engine from scratch, plus, it would have been better, because I am usualy stuck with using what ever heads were on it, and some of the parts. Now, the way I see it, I re-build, and tweak on at least 10 a year, because they are so lame. Plus, they are re-energizing the core supply.
